Abstract

PURPOSE:To suppress noise such as booming sound in a car cabin by reducing returning vibrations of a crank shaft at the time of locking-up (directly coupled). CONSTITUTION:A pump impeller 5 is fixed to a crank shaft 1 through a drive plate 2, and a converter cover 12 at which a lockup clutch 29 joins and this pump impeller 5 are tied together by a spring 11 resiliently in the rotating direction. As a result, the inertia moment of the drive plate 2 and pump impeller 5 is applied to the crank shaft 1 at the time of locking-up, so that the variation in the engine rotation is absorbed effectively. Because coupled directly with the output shaft 7 via the lockup clutch 29, the converter cover 12 functions as an inertia mass body on the output shaft 7.

参照）。[Prior Art] In recent years, automatic transmissions installed in automobiles connect the engine crankshaft and the converter cover of the torque converter with a torsion damper, and the torsion damper absorbs the impact force caused by torque fluctuations on the engine side. It is supposed to be done. As a result, even when torque is directly transmitted from the input side (converter cover) to the output side (output shaft) without going through a fluid transmission device (so-called lockup), the power from the engine side is smoothly transmitted to the output side. (For example, see Japanese Utility Model Application Publication No. 57-100653).

However, there have been cases where variations in engine rotation cannot be sufficiently absorbed, resulting in problems such as increased torsional vibration of the crankshaft and resulting abnormal noises such as muffled noise in the vehicle interior.
